Enum FrameError 

#[non_exhaustive]
pub enum FrameError {
    UnknownMessageType(u16),
    Decode {
        message_type: u16,
    },
    Decrypt,
    Malformed(String),
}

A frame arrived but could not be decoded into a [crate::parser::ProtoMessage].

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

UnknownMessageType(u16)

A well-formed frame carrying a message type this build does not know.

Safe to skip: the connection stays healthy. This is the forward-compat path for message types added by newer ESPHome versions.

Decode

A recognized message type whose protobuf body failed to decode.

Fields

message_type: u16

The message type byte that failed to decode.

Decrypt

AEAD decryption of an encrypted frame failed (tampered ciphertext or a desynchronized cipher).

Malformed(String)

The frame itself was malformed (bad length varint, wrong preamble byte, truncated payload, oversized frame, …).

Trait Implementations

impl Debug for FrameError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for FrameError

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for FrameError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<FrameError> for Error

fn from(source: FrameError) -> Self

Converts to this type from the input type.
